Castle have renewed their LCD monitor offer for the winter so you can get "a warm winter glow" (presumably from the monitor). When you buy an IYONIX, a Panther or a X100 you can get the following monitors:

• 17 inch LCD (1280 x 1024) Was ukp 164 NOW ukp 110
  
• 19 inch LCD (1280 x 1024) Was ukp 420 NOW ukp 200
  
• 20 inch LCD (1600 x 1200) Was ukp 614 NOW ukp 560

From the press release it seems that the DIY IYONIX is not included on the offer which ends on 31st January 2005.
